Best Flea And Tick Shampoo For Dogs


We’ve chosen our top picks based on how effective they are, the combination of safe ingredients, their reputation, customer feedback, and pricing.

Best Overall: Adams Plus Flea & Tick Shampoo With Precor

Adams Plus Flea & Tick Shampoo With Precor

View on Amazon

The most popular flea killer shampoo for dogs on the market, Adams Plus is extremely effective in killing fleas, flea eggs, flea larvae, ticks, and lice. It’s fast-acting and provides 28 days of control for pre-adult fleas. This shampoo is medicated with methoprene, pyrethrins, and piperonyl butoxide, but it contains very low levels that are considered safe for both dogs and cats.

Adams Plus is also formulated with soothing aloe, lanolin, coconut extract, and oatmeal to be easy on sensitive skin. Many pet parents say it’s a fantastic flea killer, has a pleasant scent, and leaves their dogs’ coats super soft and shiny. Safe for dogs 12 weeks and older.

Best Overall (Runner-Up): Vet’s Best Flea and Tick Advanced Strength

Vet’s Best Flea and Tick Advanced Strength

View on Amazon

If you’re not a fan of chemicals, this Vet’s Best Advanced Strength shampoo uses a blend of essential oils to get the job done. And many pet parents say it’s quite effective. It’s vet-formulated to kill fleas, flea eggs, flea larvae, and ticks on contact. While some customers raise concerns over essential-oil toxicity in dogs, this shampoo contains heavily-diluted amounts of thyme, peppermint, clove, rosemary, and cedarwood oils.

These essential oil concentrations are generally considered safe for dogs, but cats are particularly sensitive to essential oils. So, this product isn’t recommended for cats. Some users said the shampoo’s odor is too strong, but others like the scent. Safe for dogs 12 weeks and older.


Best Natural: TropiClean Natural Flea & Tick Shampoo For Dogs

TropiClean Natural Flea & Tick Shampoo For Dogs

View on Amazon

TropiClean is another extremely popular dog flea shampoo that contains safe concentrations of essential oils (clove, lemongrass, cedarwood, cinnamon, and sesame) as active ingredients. It’s formulated to kill adult fleas, flea eggs, flea larvae, and ticks, but it only provides seven days of flea control.

One thing to note about this shampoo is that it contains the anionic detergent and surfactant sodium lauryl sulfate (SLS), a chemical compound commonly used in shampoos and cleaning products to create a lather. While SLS can be naturally-derived or synthetic, the plant-derived SLS in TropiClean is all-natural.

While SLS may cause mild eye irritation in pets, scientists consider it safe in small concentrations in pet shampoo. We wanted to address this issue because there’s a lot of misinformation out there about SLS causing cataracts or permanent eye damage in dogs.

This product isn’t recommended for cats due to heightened essential oil sensitivity. Safe for dogs 12 weeks and older.


Best Budget: Sentry Oatmeal Flea And Tick Shampoo

Sentry Oatmeal Flea And Tick Shampoo

If you have multiple dogs in your home and are facing an unfortunate outbreak of fleas, you may be looking for the best bang for your buck in a flea shampoo. If so, this Sentry product could be a good solution. Permethrin, a synthetic insecticide of the pyrethroid class, is the active ingredient in this shampoo. It’s safe for dogs but toxic in cats until it dries, so avoid using this product on cats.

It also contains oatmeal to soothe itchy and dry skin and is great at conditioning your pup’s coat. The downside is that it only kills adult fleas and ticks but not flea eggs or larvae. And it only provides 10 days of flea control. Safe for dogs 12 weeks and older.


Best For Puppies: Biosilk Tearless Puppy Shampoo

Biosilk Tearless Puppy Shampoo

View on Amazon

Unfortunately, you should avoid shampoos formulated to treat fleas on puppies under 12 weeks of age because they’re too strong for their young bodies. While it won’t kill or deter fleas, this alternative puppy flea shampoo features soothing ingredients like milk protein, aloe vera, honey, chamomile, and vitamin E that can help relieve your youngin’s itchy skin from flea bites.

This shampoo is safe for puppies eight weeks and older. Some tips on managing fleas on little ones include:

  • Bathe your puppy frequently to help control flea infestations.
  • If you’ve spotted a few fleas on your puppy, use a metal, fine-toothed flea comb to remove them from your pup after bathing. Swish your comb into soapy water to drown the fleas you’ve removed on your comb. You may need to repeat this process several times over your puppy’s entire body to find all of them.
  • If your young puppy has a major flea infestation, contact your veterinarian as soon as possible for expert treatment.
